SPECIFICATION formingpart of Letters Patent No. 292,442, dated January22, 188,4.

Application filed October 81, ltlSB. (No model.)

ro all whom, t 7nwy'00ncern:

vBe it known that I, GRARLEs E. MURRAY, a citizen of the United States,and a resident of Brandt, in the county of Miami and State of Ohio, haveinvented certain newv and useful Improvements in VindoWSprings; and I dohereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, which-form a part of this speciication,and in which- Figure 1 is a vertical sectional view of a portion of aWindow frame and sash provided with my improved spring. Fig. 2 is aperspective view of a portion of the sash and the spring, and Fig. 3 isa detail View of the spring detached.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has 'relation to springs secured upon the frame or sash ofa window, serving to hold the sash raised by the friction between thatedge of the sash opposite to the spr-ing and the Way in which that sideof the sash slides; and it consists in the improved construction andcombination of parts of a double spiral spring adapted to be secured ina recess in the frameof sash of the window, and to bearagainst theopposite way or surface, the spring being so constructed that onlyone-half of the tension ofthe spring has to be overcome in raising orlowering the sash, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the window-frame, Bthe sash, and

' ing the sash to move,

C a recess in the edge of the said sash, in .which the spring D issecured. The spring consists of one piece of wire consisting of acentral straight piece, E, .bent at its ends to form two spirals, F,coiled in opposite directions, and the ends of these spirals are passedin opposite directions, as shown at G, parallel, or nearly so, with thestraight piece, and bent at their outer ends, H, which are inserted intothe bottom of the recess. It willvbe seen that both spirals willserve toforce the straight central portion of the spring out against theopposite surface, against which it will bind by friction and hold thesash, and it will also be seen that in raising or lowering the sash theportion of the spring facing toward the direction ofthe motion will becompressed, allowforming less resistance than the entire spring.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- The combination ofthe frame of awindow, the sash having a recess in its edge, and a spring consisting ofa straight portion, having i.

its ends coiled in opposite directions,the ends of which coils arepassed back in opposite directions and secured in the bottom of therecess, as and for forth.

In testimony .that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.

v CHARLES E. MURRAY.
